Network meta-analysis of four kinds of traditional Chinese exercise therapy in the treatment of type 2 diabetes: protocol for a systematic review

INTRODUCTION: Traditional Chinese exercise therapy, as one of the commonly used exercise interventions for the treatment of type 2 diabetes patients in China, has been proven effective by many clinical practices, but there is still a lack of evidence-based research. This study aims to integrate clinical randomised controlled correlations via network meta-analysis evidence. METHODS AND ANALYSIS: The comprehensive search included Chinese and other language databases such as the MEDLINE (PubMed), Web of Science, Excerpt Medica Database (EMBASE), The Cochrane Library, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, China Scientific Journal Database (VIP), China Biomedical Literature Database (CBM). Clinical randomised controlled trials of four traditional Chinese exercise therapies in the treatment of type 2 diabetes, including Tai Chi, Ba Duan Jin, Yi Jin Jing and Wu Qin Xi were retrieved. The search time was conducted from the establishment of the database to 30 October 2020. Two researchers screened the documents that met the inclusion criteria, extracted data according to the preset table, and evaluated the methodological quality of the included studies according to the quality evaluation tools recommended by the Cochrane System Reviewer Manual V.5.1. The R language and ADDIS statistical software were used to conduct statistics and analysis of intervention measures. PROSPERO REGISTRATION NUMBER: CRD42020214786
